Overview of the Fit Forecast with default engine option

You can use the Fit Forecast with default engine option to call the forecast engine, only if the permission (Execute Generate Forecasts in [Module]) and the rv_forecast_settings parameter is specified for the worksheet.

The rv_forecast_settings properties:

  • engine: The name of the forecast engine.
  • itemlevel: The item level at which the forecast must be calculated, that is, at the level of the selected passed item or below. If not defined, the forecast engine settings are used.
  • locationlevel: The location level at which the forecast must be calculated, that is, at the level of the selected passed location selection or below. If not defined, the forecast engine settings are used.

The parameters that are passed to the GenerateForecast command:

  • Engine Name: Based on the properties specified for the rv_forecast_settings engine.
  • Item element selection: The value is defaulted from the worksheet.
  • Location element selection: The value is defaulted from the worksheet.
  • Item Hierarchy level: Based on the properties specified for the rv_forecast_settings itemlevel. If not specified, the forecast engine settings are used.
  • Location Hierarchy level: Based on the properties specified for the rv_forecast_settings locationlevel. If not specified, the forecast engine settings are used.
  • Period level: The value is defaulted from the forecast engine settings.
  • Algorithm: The value is defaulted from the forecast engine settings (if applicable).
  • Spreading Measure Code: The value is defaulted from the forecast engine settings.

When the Generate Forecasts process is started, you can view the details of the progress of the forecast in the Job Manager.

If the Item and/or Location specified in the data context is a My Selection, a check is carried out to ensure that the Item and/or Location Level in the Default Forecast Engine is set to the base level of the hierarchy used in the My Selection, as specified in the Cycle. If the Item and/or Location level in the Default Forecast Engine is not set to the base level, the execution of the forecast engine fails, and this message is displayed:

"Item Level" must be set to the base level of the Hierarchy used in the My Selection, specified in the Cycle.

"Location Level" must be set to the base level of the Hierarchy used in the My Selection, specified  in the Cycle.
